Abstract
A substantially lofty non-woven fabric abrasive material includes: a non-woven fabric composed of randomly arrayed fibers; an adhesive agent adhered to the fibers of the non-woven fabric; and abrasive particles adhered to the non-woven fabric by the adhesive agent; wherein the abrasive particles contain soft large-sized particles and hard small-sized particles.
Description
NON-WOVEN FABRIC ABRASIVE MATERIAL
Background The present invention relates to a non-woven fabric abrasive material, and particularly a non-woven fabric abrasive material for removing fouling, scorching and clouding which adhere to materials such as metal, plastics and glass.
A non-woven fabric abrasive material has been widely known which comprises a substrate such as a non-woven fabric, an adhesive agent provided on a surface of the substrate and abrasive particles provided on the surface of the substrate, at least a part of which is buried in the adhesive agent. For example, an abrasive pad composed of a non-woven fabric abrasive material with a low density is frequently used for polishing pots and pans also in ordinary households.
Among such pads, a commercial product bringing a greatly favorable result includes a commercial product under the trade name of Scotch Brite manufactured by 3M Company. Typically, such an abrasive pad can be manufactured by a method disclosed in US Patent No. 2,958,593 (Hoover et al.).
With regard to these abrasive pads, two kinds of an abrasive pad with an abrasive agent and an abrasive pad without an abrasive agent are generally put on the market, and alternatively a type such that this pad and a sponge of urethane or cellulose are stuck together is also put on the market. A pad with an abrasive agent is used for polishing ceramic tableware and cooking utensils and the bottom of pans, while a pad without an abrasive agent or a sponge surface of a pad of a sticking type is used for polishing unscorched metal surfaces and plastic tableware and cooking utensils.
This results from the usefulness of an abrasive pad with an abrasive agent for removing various kinds of fouling such as tea incrustations and yellowing which adhere to ceramics, other general fouling and scorching of pans, while the abrasive pad with an abrasive agent leaves a scar on the surface of soft materials such as metal, glass and plastic. A conventional abrasive pad, therefore, insufficiently removes fouling and seriously scratches the surface of materials to be polished if the proper use thereof is wrong or the presence of an abrasive agent is mistaken.
This is also the case for the abrasive materials which have various abrasive particles, that is, a soft abrasive agent, a hard abrasive agent or a mixture thereof, which are adhered to fibers of the non-woven fabric, as described in Japanese Patent Laid-open Publication No. H3(1991)-14666, and damaging a surface of soft materials is not able to sufficiently be prevented with using the above described abrasive particles.
So damaging with abrasive materials of materials to be abraded, may be prevented as abrasive particles having small particle size are employed.
Abrasive particles having small particle size are actually employed for lapping.

So damaging with abrasive materials of materials to be abraded, may be prevented as abrasive particles having small particle size are employed.
Abrasive particles having small particle size are actually employed for lapping.
However, such an abrasive pad is poor in abrasive power, which is not effective for polishing ceramics and the bottom of pans and removing hard fouling. Also, Japanese Patent Laid-open Publication No. S62(1987)-88569 discloses that an abrasive pad containing abrasive particles in a range of 12 H.K. to 60 H.K. in Knoop hardness (polymer particles such as polyester, polymethacrylate, polycarbonate and polystyrene) allows scorching to be removed without scratching cooking utensils. This abrasive pad, however, has an insufficient abrasive power and thereby does not allow hard and thin film-like fouling to be removed, such as dull fouling of metallic parts and tea incrustations adhering to ceramics, among fouling in cookery and of cooking utensils.
An attempt to manufacture a pad having a surface of an abrasive and a surface for burnishing has been also made in US Patent No. 3171151, which requires precise manufacturing processes and does not obtain a bulky abrasive pad.
Summary The present invention overcomes the above-mentioned shortcomings by providing a substantially lofty non-woven fabric abrasive material which conveniently and effectively removes soft and hard fouling stuck to materials to be abraded, without damaging the materials to be abraded.
The present invention provides a non-woven fabric abrasive material comprising a non-woven fabric composed of randomly arrayed fibers; an adhesive agent adhered to the fibers of the non-woven fabric; and abrasive particles adhered to the non-woven fabric by the adhesive agent, in which the abrasive particles contain soft large-sized particles and hard small-sized particles, whereby the above-mentioned object is attained.
Two kinds of abrasive particles having different particle diameters can properly contact with a surface to be polished without hiding each other by the elasticity of a non-woven fabric (spring effect), whereby performing the abrasive power characteristic of each of the abrasive particles. Consequently, this pad has a low possibility of scratching a surface in polishing cookery, cooking utensils and tableware to be washed, and also one pad can remove scorching of pots and pans, dull fouling of metallic and glasses, tea incrustations and the like. Further, an effect of polishing metal parts is obtained with the abrasive particles being controlled in a certain range.
Detailed Description A non-woven fabric employed in the present invention is a lofty open-structured sheet material made of randomly arrayed fibers. A bulky open-structured sheet material is abundant in elasticity, and two kinds of abrasive particles having different particle diameters can properly contact with a surface to be polished by spring effect. It is preferred that a non-woven fabric is a material well known as a substrate of a non-woven fabric abrasive material to those skilled in the art. A typical non-woven fabric is described, for example, on Japanese Patent Laid-Open Publication No. H2(1990)-124272.

Detailed Description A non-woven fabric employed in the present invention is a lofty open-structured sheet material made of randomly arrayed fibers. A bulky open-structured sheet material is abundant in elasticity, and two kinds of abrasive particles having different particle diameters can properly contact with a surface to be polished by spring effect. It is preferred that a non-woven fabric is a material well known as a substrate of a non-woven fabric abrasive material to those skilled in the art. A typical non-woven fabric is described, for example, on Japanese Patent Laid-Open Publication No. H2(1990)-124272.
A preferable non-woven fabric is composed of a thermoplastic organic fiber such as polyamide (such as nylon 6 and nylon 6.6 composed of polycaprolactam and polyhexamethyladipamide), polyolefin (such as polypropylene and polyethylene), polyester (such as polyethylene terephthalate) and polycarbonate. A non-woven fabric composed of nylon and polyester fibers is generally used.
The thickness of a fiber is generally approximately 19 to 250 gm in diameter.
The thickness of a non-woven fabric is generally approximately 2 to 50 mm.
Arrayed fibers have crossings and contact points mutually bonded by frictional force, adhesive agent force and the like. The adhesion of fibers may be performed by the melting of the fibers themselves or the use of an adhesive agent.
An adhesive agent is used for bonding fibers of a non-woven fabric or fibers of a non-woven fabric with abrasive particles. An adhesive agent for bonding fibers of a non-woven fabric may be different from, or same as an abrasive agent for bonding fibers of a non-woven fabric with abrasive particles. In the case when the same abrasive agent is employed, bonding fibers of a non-woven fabric and bonding fibers of a non-woven fabric with abrasive particles may be conducted at the same time in production method.
In general, an adhesive agent contains a binder resin and an additive as a component. A binder resin means an organic resin offering the function of bonding a substance by the change of a coatable liquid to a stiff solid. Also, an adhesive agent precursor particularly means an adhesive agent in a liquid state.
An adhesive agent used for bonding fibers of a non-woven fabric can involve a thermosetting adhesive agent such as an aqueous suspension and an organic solvent solution of epoxy, melamine, phenol, isocyanate and isocyanurate resins, or a rubber-based polymer solution or suspension such as SBR, SBS
and SIS. These adhesive agents are used for being applied to fibers by an immersion coating method, a roll coating method, a spray coating method and the like so as to be thermoset.
Abrasive particles employed in the present invention are a mixture of soft particles and hard particles. Soft particles have a Mohs hardness within a range of 1 to 7, preferably 2 to 4. A Mohs hardness of less than 1 in soft particles brings an insufficient abrasive power to an abrasive pad, while a Mohs hardness of more than 7 therein brings the possibility of scratching a surface to be polished. The material of soft particles is an inorganic material such as garnet, flint, silica, pumice stone and calcium carbonate, an organic polymer material such as polyester, polyvinyl chloride, methacrylate, methyl methacrylate, polycarbonate and polystyrene, and the like.
Soft particles are required to have a large size as compared with hard particles. For example, the particle diameter of soft large-sized particles is to 1000 times, preferably 30 to 100 times the particle diameter of hard small-sized particles. If the particle diameter of soft large-sized particles is less than times the particle diameter of hard small-sized particles, then the abrasive power of an abrasive pad is rendered insufficient and a surface to be polished is scratched.
Specifically, the average particle diameter of soft large-sized particles is 0.1 to 1 mm, preferably 0.1 to 0.3 mm. For example, the particles of No. 20 to 120, preferably No. 20 to 54 in Japanese Industrial Standard (JIS) R6001 are included in this range. An average particle diameter of less than 0.1 mm in soft large-sized particles brings difficulty in removing thick fouling such as scorching, while an average particle diameter of more than 1 mm therein brings difficulty in holding themselves properly.
Hard particles have a Mohs hardness within a range of 8 or more, preferably 8 to 9. A Mohs hardness of less than 8 in hard particles brings a weak function of removing hard and thin film-like fouling such as dull fouling of metallic parts and tea incrustations adhering to ceramics. The material of hard particles is silicon carbide, aluminum oxide, topaz, fusion alumina-zirconia, boron nitride, tungsten carbide, silicon nitride and the like.
The average particle diameter of hard small-sized particles is 1 to 10 um, preferably 3 to 7 gm. For example, the particles of No. 1000 to 8000, preferably No.3000 to 6000 in JIS R6001 are included in this range. An average particle diameter of less than 1 um in hard small-sized particles brings substantially impossible in removing hard and thin film-like fouling, while an average particle diameter of more than 10 gm therein brings large level in scratching.
Combination ratio of the soft large-sized particles and the hard small-sized particles is useful in the range of from 1:9 to 9:1. If the soft large-sized particles is larger in quantity than the range, it becomes difficult to remove hard and thin film-like fouling such as dull fouling of metal, whereas if the hard small-sized particles is larger in quantity than the range, it becomes difficult to remove soft and thick fouling such as food scorch fouling. More preferred combination range is that the soft large-sized particles are larger in quantity than a combination ratio of 2:8 in order to keep advantage due to the soft large-sized particles and the hard small-sized particles as long as possible, whereas the soft large-sized particles are smaller in quantity than a ratio of 7:3 from the view of a coating process as too large quantity of soft large-sized particles decreases flowing ability of a combined liquid.
An adhesive agent for bonding fibers of a non-woven fabric and abrasive particles may be aqueous or solvent-based. An adhesive agent after being thermoset preferably denotes substantially the same hardness as soft large-sized particles. If the hardness of an adhesive agent is substantially lower than that of soft large-sized particles, then the adhesive agent covers up the soft large-sized particles, and abrasive power becomes poor.. If the hardness of an adhesive agent is substantially higher than that of soft large-sized particles, then a surface to be polished is possibly scratched. A binder resin of an adhesive agent to be used can involve epoxy, melamine, phenol, isocyanate and isocyanurate resins, and the like. A particularly preferably binder resin is a phenol resin, an epoxy resin and the like.
A non-woven fabric abrasive material of the present invention can be produced in accordance with a method known to those skilled in the art. For example, abrasive particles are first added to an adhesive agent precursor and dispersed thereinto with a sufficient uniformity so as to obtain a dispersion solution. The dispersion solution is applied on the surface of fibers of a non-woven fabric. It is preferred that an applying method to be used is an immersion coating method, a roll coating method, a spray coating method and the like.
Soft large-sized particles and hard small-sized particles may be projected into the same adhesive agent precursor and concurrently applied, or projected into different adhesive agent precursors and separately applied. Also, an adhesive agent precursor is previously applied to a non-woven fabric, and then abrasive particles may be sprayed thereon.
In the case of using a thermosetting resin as a binder resin, the adhesive agent precursor is thereafter thermoset by heating for a certain time. In general, an adhesive agent precursor is thermoset by maintaining at a temperature of 100 to 3000C for 10 to 30 minutes.
The thickness of a fiber is generally approximately 19 to 250 gm in diameter.
The thickness of a non-woven fabric is generally approximately 2 to 50 mm.

The detergency of the resulting abrasive pad was evaluated by the following tests. The results are shown in Table 7.
1) Scorch Fouling Removal Test (Food Soil Removal Test) A stainless plate with scorch fouling same as that employed in Examples 1 to 7 was prepared. The abrasive pad was allowed to move go and back with a valid pad area of 49.59 cm2 (5.7 cm x 8.7 cm), a pressure of 48.09 g/cm2, a speed of 45 roundtrip / min and a stroke of 35 cm to rub the stainless plate with scorch fouling having a default area of 114 cm2 (5.0 cm x 22.8 cm). In every 20 times go and back, deterged area was calculated in an area of 36.1.cm2 (19 cm x 1.9 cm)which was located at the middle of the plate. This was repeated until 90% of the area was deterged, and times required for 100%
detergency was calculated with being approximation to secondary curve on the least-squares method. Shown is a converted value based on the calculated times as a value for Comparative Example 1(no particulate abrasives) is assumed to be 100.
2) Stainless Dull Fouling (Surface Oxide) Removal Test A stainless steel plate was uniformly rubbed with "SCOTCH BRITE A 11"
manufactured by Sumitomo 3M to make the surface to have a gloss (20 degree gloss) of 20 to 40. "Micro-Tri Gloss Meter" manufactured by BYK-Gardner Corporation was employed for the gloss measurement. The stainless plate was burned with a gas range to put burned color as the "dull fouling". It was confirmed that the surface had a 20 degree gloss of not more than about 25.
With using "PUSH PULL TESTER" manufactured by Toyo Seiki K.K., the stainless plate was rubbed at a speed of 45, for ten times go and back, at abrasive angles of -35, 0, and +35 degrees. In every unit of repetition (every 30 times), 20 degree gloss was measured. A Gloss value resulted fiom 150 times abrasion was calculated with being approximation to secondary curve on the least-squares method, and shown.
3) Glass Friction Test An abrasive pad was applied to the surface of a glass plate, which was rubbed with a hand for 10 times go and back. It was evaluated under the following standards how seriously the rubbed surface was scratched.

Through the Examples 16, 13, 14, 15, and Comparative Example 5, scratches resulted from the particulate abrasives having a size of No. 2000 to 3000 have a fineness which is close to visible limitations, and they are substantially invisible. When the size is not less than No. 4000, the resulting scratches become below the optically visible limitations, and scratches substantially are not formed. That is, the particulate abrasives having a size of not more than No. 2000 are effective from the view of scratching property, whereas the larger size, that is No. 2000 is more effective than No. 4000, or than No. 6000, from the view of removing dull fouling and of improving gloss.
As a whole of the above, the preferred range of the particulate abrasive size is from No. 3000 to No. 6000. The particulate abrasives employed in Examples 8 and 9 are based on zirconia-containing alumina, and substantially the same performance were obtained.
